If you like the QGD, you can play 1...e6 2...d5 and see if White is interested in maintaining his English approach to the game.
I couldn't have said it any better.
1)...e6!
2) Nc3, d5
The most natural way to play from here would be:
3) d4, Be7
3) d4, Bb4
3) cxd5, exd5 4) d4, Nf6
Hello QGD! That's if you like getting into these kind of games.
It's all a matter of taste, just just need to know what type of game suits you with Black.
1 ...c6 is an annoying move for an English player. Quite fine if Black plays Slavic or Semi-Slavic vs Q Gambit and also plays Caro_Kann vs 1 e4. If White won't play d4 or e4 early, then Black just uses aReti set up with Bf5 or Bg4. Very solid approach. Less need to study opening theory for Black if Caro-Kann and Slav is what you do.
e5 is a Sicilian down a tempo, c5 is more placid but drawish, Nf6 is most flexible.All have a lot of book theory.
Kasparov tried 1 ..g6 with good results - fine if you can play reverse Grand Prix, Modern Averbakh or King's Indian, depending on what white does. Requires the most flexibility. Most interesting if you're looking for complexity and good counterattacking chances. Look up some Kasparov's game to see how he played it.
